The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0030] Example 1

[0031] Please refer to Figures 1 to 5 A top cover clamping and flipping mechanism includes: at least two clamping components, each clamping component includes a driving member 1, a clamping arm 2 that can clamp toward the workpiece 7 in the length direction of the workpiece 7 or move away from the workpiece 7 to release, and a limiting member 3 that limits the width direction of the workpiece 7; a flipping component, the flipping component is used to drive the clamping component to flip; and a lifting component 6, the lifting component 6 is used to drive the flipping component and the clamping component to rise and fall together.

[0032] According to a preferred embodiment, the flipping assembly includes a servo motor 4 and a rotating shaft 5 , one end of the rotating shaft 5 is connected to the output end of the servo motor 4 , and the clamping assemblies are all arranged on the rotating shaft 5 .

[0033] According to a preferred embodiment, a plurality of clamping assemblies are evenly distributed in a ring array around the rotating shaft 5. Four clamping assemblies or six clamping assemblies can be selected to be evenly distributed on the rotating shaft 5.

[0034] According to a preferred embodiment, the number of the clamping assemblies is two, and the two clamping assemblies are symmetrically arranged about the rotation axis 5 .

[0035] According to a preferred embodiment, the clamping arm 2 is provided with an inclined guide surface 21 and a positioning groove 22 in sequence along the inner side wall facing the rotating axis 5. The inclined guide surface 21 and the groove prompt the outer end of the workpiece 7 to slide into the positioning groove 22 so that the workpiece 7 is centered on the clamping arm 2.

[0036] According to a preferred embodiment, the stopper 3 is provided with a first end face 31 and a second end face 32 connected in sequence along the inner side wall in the direction toward the rotating shaft 5. The first end face 31 and the second end face 32 are arranged at an angle to abut and limit the short side position of the workpiece 7. In this embodiment, the first end face 31 and the second end face 32 form an obtuse angle, that is, greater than 180 degrees, so that the top cover can slide onto the second end face 32. The second end face 32 plays a supporting role for the top cover. Figure 4 As shown, the second end surface 32 is a horizontal surface.

[0037] According to a preferred embodiment, the stopper 3 and the driving member 1 are both fixed on the rotating shaft 5, and a plurality of stoppers 3 and a plurality of clamping arms 2 are arranged to enclose a workpiece position, and a plurality of stoppers 3 of each clamping assembly are respectively arranged on the front and rear sides of the workpiece position and are symmetrically arranged with respect to the workpiece position, and a plurality of clamping arms 2 of each clamping assembly are respectively arranged on the left and right sides of the workpiece position and are symmetrically arranged with respect to the workpiece position. Figure 5 As shown, the direction of the workpiece 7 toward the clamping arm 2 is the left and right directions, that is, the direction pointed by the arrow A, and the direction of the workpiece 7 toward the limiter 3 is the front and back directions. In this embodiment, each clamping assembly includes 4 limiters 3, 2 clamping arms 2 and corresponding driving members 1. Since the top cover is rectangular, the 4 limiters 3 are distributed diagonally in a rectangular shape. The 4 limiters 3 limit the width of the top cover, and control the width in the front and back directions to match the top cover to avoid offset. The clamping gap between the two clamping arms 2 in the state of clamping is consistent with the length of the top cover to avoid the top cover being damaged or loosened and offset due to too small a gap, too high a pressure or too large a gap. The clamping gap is the most suitable distance between the two clamping arms 2 and used to clamp the workpiece 7 in the length direction.

[0038] According to a preferred embodiment, a diffuse reflection sensor is further included for detecting the workpiece 7, and the lifting assembly 6 is a linear module. The diffuse reflection sensor is used to detect whether the workpiece 7, i.e., the top cover, is between the two clamping arms 2, i.e., whether it is at the workpiece position.

[0039] According to a preferred embodiment, the bottom wall of the positioning groove 22 is on the same horizontal plane as the second end surface 32. Figure 5 For reference, the direction perpendicular to direction A and downward is the bottom wall direction of the positioning groove 22. The bottom wall of the positioning groove 22 and the second end face 32 are in the same horizontal plane. In this embodiment, the bottom wall of the positioning groove 22 and the second end face 32 are both horizontal planes, which are used to support the bottom wall of the top cover (horizontally set).

[0040] According to a preferred embodiment, the straight-line distance between the end of the inclined guide surface 21 close to the positioning groove 22 and the positioning groove 22 is greater than or equal to the outer end thickness of the workpiece 7. Figure 3 The top cover can be divided into a first part and a second part from top to bottom. The distance between the lower end of the inclined guide surface 21 and the positioning groove 22 is used to define the width of the side wall of the first part of the top cover. The positioning groove 22 is used to define the width of the bottom side wall of the top cover, that is, the side wall of the second part. The side wall of the second part of the top cover is filled into the positioning groove 22, and the first part is located in the space between the lower end of the inclined guide surface 21 and the positioning groove 22.

[0041] Working principle of the utility model: the processing part 7 mentioned in the utility model is a top cover, especially a battery top cover. This scheme is not limited to the top cover. The utility model is used to cooperate with the movement of the front and rear processes in the operation and production of the equipment. The top cover is transported and operated on the accompanying pull belt. After the top cover is in place, the top cover needs to be flipped. The clamping assembly is driven down by the lifting assembly 6, and the limit member 3 limits the top cover. The clamping arm 2 is driven by the driving member 1 to clamp the top cover from the pull belt and center it. In this embodiment, the driving member 1 is a cylinder. Further, a parallel clamping cylinder can be selected. The lifting assembly 6 is a linear lifting module. After the linear lifting module drives the clamping assembly to rise, the flipping assembly selects a motor drive, and a servo motor 4 can be selected. The servo motor 4 is directly connected to the reducer to drive the clamped top cover to rotate 180 degrees. The flipped top cover waits for the mechanism of the next workstation to dock and take materials. This structure can improve the stability of the top cover flipping and reduce the equipment failure rate.

[0042] The clamping arm 2 is fixed to the telescopic end of the cylinder, and the driving member 1 is a cylinder, such as Figure 2The telescopic end of the cylinder can drive the clamping arm 2 to move back and forth left and right. Optionally, the telescopic end of each cylinder drives a clamping arm 2 to move. When the telescopic ends of the cylinders on the same horizontal plane, that is, on the same clamping assembly, simultaneously drive the clamping arms 2 to move closer to each other, it is a clamping state. On the contrary, when they are connected and moved away, it is a loose state. The cylinders, clamping arms 2, and limit members 3 of the two clamping assemblies in this embodiment and the cylinders, clamping arms 2, and limit members 3 of another group of clamping assemblies are symmetrically arranged about the rotation axis 5. When rotated 180 degrees, that is, flipped, the workpiece 7 clamped by the other clamping assembly can be flipped at the same time or the other clamping assembly can be prepared for the next clamping, which has high work efficiency.

[0043] like Figure 2 As shown, after the clamping assembly below clamps the top cover, it rises to a certain position through the lifting assembly 6. In this embodiment, the driving motor drives the rotating shaft 5 to rotate through the reducer, and the rotating shaft 5 can drive two groups of symmetrically arranged clamping assemblies to realize the switching of the rotating stations. The top cover after flipping is detected by the diffuse reflection sensor to see if it is in place, and the signal is transmitted to the next station, and the next station performs the material picking action;

[0044] This product greatly improves the stability of top cover clamping and flipping. During the flipping process, the probability of top cover falling off, top cover displacement and dislocation, and collision is extremely low. This is because after the top cover is driven by the driving part 1 to drive the clamping arm 2 to clamp the short side, the long side is also limited by the limiting part 3 to prevent the top cover from shifting. The servo motor 4 is directly connected to the reducer to drive the rotating shaft 5 to rotate, and the acceleration and deceleration are controllable. By upgrading and optimizing this structure, the number of alarms at this station can be reduced in actual production.

[0045] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
